Katy Perry would "ditch" her singing career to be an 'American Idol' judge.

The 'I Kissed a Girl' singer - who recently joined Simon Cowell, Randy Jackson and Kara DioGuardi as a guest judge on the series - would consider quitting her pop star life for a permanent role on the TV talent show because she enjoyed how "fun" and "easy" it was.

She told MTV: "The 'American Idol' experience was awesome. If I was offered that job as a permanent host, I would ditch my career and take on that career. It's such a fun, easy thing. I mean, I guess the pressure gets really on when you start eliminating the number of people that are going through until you've got the final two. So that can be kind of tense and stressful, but otherwise it's kind of like judging a talent show."

The 25-year-old star had been looking forward to her guest slot for months and went on the programme with the aim to be an "honest ashole" like Simon.

She previously said: "I might become a little bit of a buddy with Simon, because whenever I watch that show, as much as he's an ashole, he's a very truthful, honest a*shole.

"I'm not there to build them up. It's weird, because I don't want to break their hearts, but everyone knows someone who's been doing karaoke and doing little gigs here and there, and nobody has told them that they can't sing on pitch for, like, 15 years?
